GermGuardian - AC4300WPT

Look under the cabinets where the pipes come in and see if there’s gaps. I had an apartment years ago where the smell from the lower unit was coming in through there. They put some spray foam in to block it off and it helped immensely. I have germ guardian purifiers with pet filters that I’ve had for years and they help a lot with allergens and I also smoke cannabis and it helps with that too (I live in a house so it’s just me, but it helps circulate the air and get cooking smells and cat dander out of the air too).

I have a vertical germ guardian at the back of our LR4. I don't want it too close to the opening as it'll suck in too much dust and prematurely clog the filter. I wash the prefilter once a week..

With that in mind a germ guardian tower is probably the most affordable good option. Whatever you buy should have UVC light built in to degrade mycotoxins, “plasmawave” or “bipolar ionizer” is also an acceptable alternative just make sure it’s California CARB certified. Stay away from classic ionizer/ozone

They don't really work if you have an active infestation. Ive got 4 lg ones in an 800sq ft house and I swear they do almost nothing. We even have this electrostatic filter in the hvac and still I've get systems when the doors close or the AC goes on. I have 2x airmega 200s, germ guardian rated for 900 sq ft, coway with uv rated for 600 sq ft. 2 upstairs and one down. If I were you id try to build the biggest Rosenthal filter or several as they don't get down hall ways or around stairs, etc. The think I don't like is they really tank your electric bill and are very noisy, as they have to stay on high mode.

I used this national allergy website. I got the Dyson and the germ guardian. Honestly I don't think the Dyson is worth the money. https://www.natlallergy.com/

The best bang for buck is germ guardian, and the parts are replaceable if something breaks. They sent us a replacement part for one of our units for free, no official warranty or anything. We have 3 of them that have been running for a decade in our house.

I have a germ guardian I bought in 2019 that I use in the room with a litter box and it significantly helps with the smell. I've used it before when my wife smoked up the kitchen trying to reverse sear a stream and it also helped a lot with the smoke. I know it's not one of the more suggested ones here but it's worked really well for me

I like my WINIX for these larger particles. It has a cleanable pre filter, charcoal filter and the hepa. I vacuum the pre filter weekly to get the cat fur off. I also use an old germ guardian that was my best buddy in a musty old office I worked. It’s still a great unit just louder like a fan so I use it in the bedroom as white noise now It’s worth mentioning a reminder to change the home furnace filter if you have one. I tend to change mine every 1-3 months during high allergen or fire seasons.

I have quite a few allergies, and when we adopted a dog, they became quite serious to the point I needed puffers and was rediagnosed with asthma after 20 years of no issues. I bought a Germ Guardian for the bedroom and I ran it 24/7. It was a lifesaver. I bought one for the main floor and one for the basement and they have really helped. I highly recommend getting one, at the very least for your sleeping area.

Yes! I got one at first and now we have 3! They work so well. Gets rid of weird smells, room not so stale, air noticeably cleaner. I got germ guardian but the others are different brands my Costco had. For filters, I buy the knock off brand ones that fit in my machines and they work fine but significantly cheaper than brand name filters
